PREFACE. 

The Committee on Science and the Arts of the Franklin Institute 
was organized in 1834, for the purposes expressed in the following 
quotation from the By-Laws of the Institute : 

" To perform such duties as may devolve upon them, and to 
sustain by their labors the scientific character of the Institute." 

Originally this committee consisted of such members of the 
Institute as should voluntarily enroll themselves as pledged to 
perform such work, and their reports were submitted to the Insti- 
tute for ratification. 

To this committee were referred the examination of new inven- 
tions and discoveries, and recommendations for rewards for merito- 
rious inventions. 

With the rapid progress of the arts the number of applications 
for awards greatly increased, and with it the danger of erroneous 
recommendations from a voluntary committee. In 1887, the com- 
mittee was reorganized so as to be elective, consisting of forty-five 
members, fifteen being chosen annually for a term of three years, 
and their action was accepted as the decision of the Institute. 

Up to the year 1888, about 1,500 examinations and reports had 
been made, which were simply filed away in numerical order. A 
knowledge of their contents (excepting those that had been pub- 
lished) rested only in the recollections of the members. Compara- 
tively few of the earlier members now survive. 

The value of these reports as indicating earlier states of art 
was recognized by the Committee, and in order to render them 
accessible for reference, the following preamble and resolutions 
were adopted by the Committee at their meeting of October 2, 
1889: 

•' Whereas, There have been a large number of reports prepared 
by the Committee on Science and the Arts which are not within the 
knowledge or recollection of many of the present membership of 
the Committee and are not useful or convenient for reference, 
for the reason that there is no index or catalogue setting forth 
their subject-matter, although many of these reports contain 
valuable and exact information as to the state of many arts in 
earlier periods ; 

" And, Whereas, Provision has been made without cost to the 

(iii) 



V PREFACE. 

Institute for the expense of clerical services incurred in the 
preparation of suitable subject-matter indices for said reports, 
from the first reports issued to this date, such intended indices 
being 

"(i) Of the names of applicants for examination.* 

" (2) Of the names of the inventors. 

" (3) Of the title of the invention ; and 

" (4) Of the subject-matter as classified to conform to the system 
of classification now employed in the U. S. Patent Office ; 

" Therefore Resolved, that a committee be appointed to super- 
vise the preparation of said indices and that upon the completion 
thereof, all subsequent reports be immediately added to said indices 
as soon as final action of the Committee is taken thereon." 

The sub-committee was appointed by the Chair as follows : 
Messrs. Cheney (Chairman), Heyl, Hexamer, Leclere and Wiegand. 

The compilation of the Index, under the direction of the Com- 
mittee, was completed in December, 1889, and by the Committee 
on Science and the Arts was reported to the Institute, and by the 
Institute referred to the Board of Managers, which directed its 
publication. 

Provision has been made by the Secretary to index in like 
manner all subsequent reports, so that hereafter the record of the 
researches of the committee will readily be accessible. 

Applications upon which, from lack of data or other reason, 
no report was made, are indicated in the Index by an asterisk (*). 
In such case, however, the records, which are accessible, will 
generally be found to contain a complete history of the case. 

The compilation of this Index and the supervision of its publi- 
cation were done by Mr. Percy A. Bivins, to whom the Committee's 
acknowledgments are due for the intelligent and thorough execu- 
tion of the work. 

The Committee. 



* The records of the names of applicants was so incomplete, that it was 
found impracticable to make an index of them as stated in the resolution. 
The indexing by names of the inventors is complete.

I^HK JOURNAI^ 

OF THE 

KRANKIvIN INSTITU 

Devoted to Science and the Mechanic Arts 



028 099 068 1 




The Journal of the Franklin Institute is issued in monthly 
parts of not less than eighty pages each, liberally illustrated, and form- 
ing two volumes annually. 

Its objects are to encourage and promote original research, and to 
disseminate knowledge in all that relates to the application of science 
to the useful arts, and especially in the fields of engineering and the 
mechanic arts. 

The impression for December, i888, completed the 126th volume 
of the Journal, and the sixty-third year of its existence, and the cur- 
rent volume commences with very favorable prospects.. 

The Journal is edited under the direction of the Committee on 
Publications, with the assistance of the Secretary of the Institute, 
and of a staif of able collaborators. In addition to numerous original 
contributions, covering the widest range of applied science, the Jour- 
nal contains the record of the educational and scientific work of the 
Institute, many of the lectures, the papers read and discussed, the 
reports of its committees, the proceedings of its meetings, etc., which 
should especially commend it to the favor of the members. It has no 
personal pecuniary interests to subserve, and the efforts of all concerned 
in its publication are directed solely with the view of maintaining the 
high reputation it has earned during more than half a century as a lead- 
ing journal of technology and a standard work of reference. 

The considerable circulation of the Journal among men of science, 
engineers, manufacturers and societies and public institutions, at home 
and abroad, will be received by discriminating advertisers as fair evi- 
dence of its value as an advertising medium. The Committee admits 
none but- the best class of advertisers to its business columns.
